I live on a one block street that is a dead end. You have to be going here to get here so I look out for everybody on the street. I'm not the only one. I also keep odd hours so am up in the middle of the night and check every vehicle on the street.
But no, I have no idea generally what my neighbors are doing unless they tell me, and then I'll forget :)
We also live in a dead-end street!)) We just bought a house and moved here, we haven't met all the neighbors yet!))
